Erratum to: J Neurooncol DOI 10.1007/s11060-015-1940-9

In the original publication there are errors in the captions to Figs. 2–4 and in the references to these figures in the text. The captions should have read as follows:

Fig. 2 Characteristic histological features of chordoid meningiomas. a Chordoid meningioma demonstrating chord-like arrangement of eosinophilic tumor cells with a background of mucoid matrix (hematoxylin‐phoxyn‐saffron: HPS, bar 100 μm). b Alcian Blue positivity within the mucoid matrix (Alcian Blue/HE, bar 100 μm).

Fig. 3 Kaplan–Meier curve for all patients included within the study. 3- and 5-year PFS was 76.0 and 67.5 %, respectively

Fig. 4 Kaplan–Meier analysis of recurrence free survival following either gross (GTR) to subtotal (STR) resection. Greater extent of surgery was associated with improved rates of tumor control. For GTR, 3- and 5-year PFS was 85.3 and 80.8 %, respectively. For STR, 3- and 5-year PFS was 50.7 and 33.8 %, respectively, p < 0.001

The references to these three figures in the text should have been placed as follows:

Figure 2 should have been cited in the Introduction after the citation of Kepes et al. [4].

The reference to Fig. 2 in the Outcomes section (page 5) should have been to Fig. 3.

The reference to Fig. 3 in the Prognostic factors section (page 6) should have been to Fig. 4 and the existing reference to Fig. 4 in that section should have been removed.
